As Allen had established his reputation by 1745, he must have been active for some years previously and his career probably began in the 1730s. Very few players were mentioned by name in contemporary reports and there are no other references to Allen. One source says he may have played in 1751 in a match between Kent and Hampshire.

The episode's title refers to the hex key that Michael makes from a screw, the key being named "Allen Schweitzer 11121147". Also in this episode, Veronica Donovan continues her investigation as to who is actually responsible to framing Lincoln Burrows on Michael's request, while at the same time, Michael deals with the impending race riot in Fox River, which could hinder his escape plans.

Plot

Michael Scofield and Fernando Sucre (Amaury Nolasco) face a lockdown in order for the guards to search cells for contraband, where they're about to throw away a knife, but were stopped by Bellick (Wade Williams), who sends Sucre to SHU. Warden Pope (Stacy Keach) calls off the search for Michael's cell, but Bellick feels determined to, and sneaks into his cell when the prisoners are away, and finds the name "Allen Schweitzer". Bellick runs the name on the database, only to find no one matching it.
